Free Oberon

Installation

Installation under OS GNU/Linux.

  1. Download Free Oberon source code from freeoberon.su in tar.gz format or from the GitHub repo. Note that the archive with the version for Windows is also suitable, because it contains the source code. Extract the archive to your home directory or to another location on the disk. (This tutorial will assume the files are extracted to the home directory.)
  2. Using terminal or in any other way, install the following packages:
  • libsdl2-dev
  • libsdl2-image-dev
  • binutils
  • gcc
  • make

The names of the packages are given in accordance with their names in the Debian GNU/Linux operating system. They are also suitable for Ubuntu, Linux Mint, Raspbian and other. To install them, run the following command:

apt-get install -y libsdl2-dev libsdl2-image-dev binutils gcc make

(This command must be executed with superuser privileges, that is, you must first run su and enter the password.) On OS Fedora, Red Hat, CentOS and others, the command and package names will differ (one the packages glibc-static or glibc-devel-static might also be required):

sudo yum install SDL2-devel SDL2_image-devel binutils gcc make       (not tested!)
  1. Go to the src subdirectory and start the compilation:
cd ~/FreeOberon/src
make -f Makefile_linux
  1. (optional) Append the following line to the end of file ~/.bashrc:
alias fo='cd ~/FreeOberon;./FreeOberon'

This will allow you to launch Free Oberon using the fo command.

Installation under Windows.

Download the setup porgram in EXE format from freeoberon.su, run it and follow the instructions.

Alternatively, you can download a version of Free Oberon in a ZIP-archive (from freeoberon.su), extract it to any place on the disk and (optionally) create a desktop shortcut.

Note. If you want to recompile Free Oberon under Windows from the source code yourself, refer to Appendix A of the Free Oberon documentation on freeoberon.su.

Usage

Run Free Oberon and type in an Oberon program (or open an example program like Book.Mod) and press F9 to compile and run the program. The module source code files are saved in subdirectory Programs and the compiled executable files are saved in bin. data/bin/compile.sh and data\bin\compile.bat are used to compile a program on GNU/Linux and Windows accordingly and can be edited if required.
